Attempts to define and clarify the concept of response uncertainty of the observer in imitation through a review of research on imitation. (CM)

Two experiments examined conditions that affect the observer's spontaneous motoric and symbolic mediation, and the relationship between these mediators in an observational learning situation. Subjects were undergraduate students. (CM)

Assessed the differential effects of single v multiple adult models on second- and third-grade children's expression of preferences when the modeled preferences are either consistent or divergent. (CM)

The impact of exposure to social models displaying variably tolerant pain behaviour on observers' expressions of pain is examined. Findings indicate substantial effects on verbal reports of pain, avoidance behaviour, psychophysiological indices, power function parameters, and sensory decision theory indices. Discussion centers on how social models…

This study investigates the possibility that the reinforcement strength of stimuli can be enhanced by observational learning as well as by pairing with unconditioned reinforcers. The reinforcement strengths of two candies were determined for 40 preschool children as measured by rate of response on a button pressing apparatus. The children then…
